5 ___________________________________ SAME SPECIES LIVING TOGETHERIN AN AREAEx: “herd”DIFFERENTPOPULATIONSLIVING TOGETHERIN AN AREA
6 _______________________ _____________ All the organisms thatlive in a place togetherwith their NON-livingenvironmentGroup of ecosystemsthat have same climateand similar communitiesThe portion of the planetin which all life exists
7 Organisms so similar to one another that they can breed and produce fertile offspring = _____________
8 EX: Horse X donkey = mule 64 chromosomes62 chromosomes63 chromosomesHorses and donkeys are different species.If you breed them, the result is a mulewhich can NOT have offspring!
9 The portion of the planet in which all life exists = _________________ The scientific study of interactions of organisms with each other and with their environment = ______________The portion of the planet in which all life exists = _________________(includes land, water, atmosphere)Extends from about8 km above the Earth’s surfaceto 11 km below the ocean’s surface
10 WHAT SHAPES AN ECOSYSTEM? __________________All the living things anorganism interacts withAll the non-living things thataffect an organismEx: climate, temperature, sunlightsoil, humidity, wind
11 = The area where an organism lives __________________= The area where an organism livesA rattlesnake lives in a desert in the American Southwest
12 _____________= place it lives PLUS the_____________ & ______________interactions it has in that placeNICHE includes: Where it lives PLUS . . .What it eats? What eats it?Where in the habitat it lives? In a tree, in a pond, undergroundIts actions… hibernating, migrating, etc When & how it reproduces?
13 HABITAT vs NICHE? Habitat is like an organism’s ____________ Habitat is like anorganism’s ____________Niche is like anorganism’s ______________
14 NO TWO SPECIES CAN SHARE THE SAME NICHE ! = ______________________________
15 The Earth is SOLAR POWERED! ALL LIVING THINGS USE ENERGYThe Earth is SOLAR POWERED!_____________ is the main source of energy for life on Earth.
16 AUTOTROPHS = PRODUCERS Can make their own food ALL LIVING THINGS USE ENERGYAUTOTROPHS = PRODUCERS Can make their own foodMost autotrophs use _______________to capture solar energyMain producers on land= green plantsIn water = algaeBIOLOGY; MIller and Levine; Prentice Hall; 2006
17 Some autotrophs can make own food in the ____________________ They use energy stored in________________ of______________________to producecarbohydrates = ___________________Ex: Bacteria thatlive in HOSTILE placesLike volcano vents, hot springs,marshesBIOLOGY; MIller and Levine; Prentice Hall; 2006
18 HETEROTROPHS = ____________ Get energy from consuming other organisms
19 HETEROTROPHS = CONSUMERS ________________ =eat only plantseat only animalseat both plants & animals
20 HETEROTROPHS = CONSUMERS ________________ =feed on plant & animal remainsEX: mites, earthworms,snails, crabsbreak down and absorb organic matterEX: bacteria & fungi
21 Energy flows through an ecosystem in a series of steps in which organisms transfer energy by being eaten_________________________________= _________________↑↑
22 In most ecosystems feeding relationships are more complex Pearson Education Inc, Publishing as Pearson Prentice HallIn most ecosystems feeding relationships are more complexA ______________ links ALL the food chains in an ecosystem together.
23 Each step in a food chain or web = _______________ ______________ ALWAYSmake up the________trophic level.
24 Lower levels must be bigger to support the level above. Only about_____ ofthe energy fromeach level is passedon.
25 Some energy is used for life processes such as growth, development, movement,metabolism,transport, andreproduction.The rest islost as ________
